从官网上下了LightSwitch_Office_Integration_Pack_Extension 安装包，在LS属性中将扩展包加入到工程。

先制做一个WORD模板 ，示意如下：注意书签和控件名

将文件复制到LS的客户端工程中，并设为内嵌的资源。

在LS客户端需要导出WORD的地方，加一个命令按钮，生成相应的事件处理：

 partial void GenerateDocument_Execute()
        {
            // Write your code here.
            string path= Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments);

            Assembly ass = Assembly.GetExecutingAssembly();
            Stream s = ass.GetManifestResourceStream(this.GetType(), "MonthPlan.docx");
            byte[] bt = new byte[s.Length];
            s.Read(bt, 0, bt.Length);
            s.Close();
            s.Dispose();
            var fileName = this.WorkPlanHeads.SelectedItem.PlanYearMonth + "工作计划";
            FileStream fs = new FileStream(path + "\\"+fileName+".docx", FileMode.Create);
            fs.Write(bt, 0, bt.Length);
            fs.Close();
            fs.Dispose();
        
            List<OfficeIntegration.ColumnMapping> planHeadColumn = new List<ColumnMapping>() {
                new ColumnMapping("PlanYear","PlanYear"),
                    new ColumnMapping("PlanMonth","PlanMonth"),
                    new ColumnMapping("FillDate","FillDate")
            };
            var doc = OfficeIntegration.Word.GenerateDocument(path + "\\"+ fileName+".docx", this.WorkPlanHeads.SelectedItem, planHeadColumn);
            List<string> detailsHeader = new List<string>() {
                "" ,"TypeName","PlanContent","WorkEmp","WorkDept","PlanEndDate","Remark"
            }; //要导到WORD中的对应的数据源中的列名，第一个为空，对应WORD中序号一列，这是在WORD模板中使用了自动编号的原因。

            OfficeIntegration.Word.ExportEntityCollection(doc, "PlanDetail", 2, false, this.WorkPlanHeads.SelectedItem.WorkPlanDetails, detailsHeader);
            OfficeIntegration.Word.SaveAsPDF(doc, path + "\\" + fileName + ".pdf", true);

        }

接下来，进行调试，可以看到LS窗口中选中的数据被导入到WORD中。但是OfficeIntegration好象没有将生成的WORD自动保存的功能。
